Any ideas on getting better fuel mileage. If it does not get better it is for sale. Only have 600 miles, getting 6.8-7.5 pulling 38 Fountain. 336 214 6900 Roger

Drive it downhill.

yu need to give it 8-10k miles before making a bailout decision...

Then what should I expect?? If it is not going to get 10-11 pulling it is outta here. How can it possibly get 60% better.

Tractor trailers get better than this truck pulling 50,000 pounds.

Roger, how fast are you towing?

With the Dmax, I get 9-10 MPG at 65 MPH pulling around 15k.

At 75, I get 7.5-8.

You mean to tell me that you have 2 very expensive offshore boats and a $65K dually....and you can't afford the gas? WTF are you thinking? The best that you can expect is another 3 miles per gallon with ANY of the other dually's towing a 35 to 38 foot boat. So 10,000 miles a year towing at 7MPG = 1429 gallons at $3.00 a gallon = $4,287. 10MPG = $3,000 annually. You cannot afford $1,287 annually or $107 a month? I do not understand these arguments given the type of total expenditures to pursue this hobby. I sold my new truck with 600 miles on it and lost $12,000 in depreciation.....but it saves me $1,287 a year? WTF?? What I can't figure out is that people say crap like this and yet somehow figure out a way to earn or borrow $500K worth of equipment??

Is it the average consumption ?
How long trips do you make ? A lot of "stop and go" or constant speed ? How fast do you go ? It all makes a difference.

EXACTLY !!

To me, it is the extra stop on a 300 mile trip that drives me nuts. I went FL, I almost went F450 but didn't like it.

And, yes, you can install extra tanks.
